The precursor solution constituted of the metal nitrates mixed with the polymer-PVA/PAA/carboxylated starch in presence of mono-/disaccharides or, poly hydroxy compound. Thermolysis/flame pyrolysis of the precursor mass at external temperatures of around 300-500°C resulted in the oxide phase. 关键词: Nanostructured materials;Oxides;Phosphates;Vanadium compounds;Molybdenum compounds;Tungsten compounds;Ceramic materials;Organic polymers;Pyrolysis;Nanosized oxides;Chemical route;Molybdate;Tungstate;Vanadate;Polymer precursor;Thermolysis
